This is so awesome! I'm living vicariously through you and I hope you don't mind. The trumpets or velocity stacks facilitate airflow into the engine by smoothing out the air flowing in. Some people say they're pretty critical but if I remember right the filter might perform that role in their place. The TPS should be just like any other TPS. As in, less than a volt at closed throttle and close to 5V at WOT. Unless it's simply a closed throttle switch but I've never come across that personally, though that doesn't mean it doesn't exist. You can check it with a DVOM set on resistance by connecting the meter and sweeping the throttle. If it's goes from X(random number) ohms to OL then it's a switch. If it smoothly changes from one value to another it's a regular TPS. Being that it's a 3 wire sensor it's likely a regular TPS. Hope that helps and trust I'm not trying to be a jerk! I just wanna see this baby in action! Have you ever heard an ITB car in person? It's pure sex!!!
Thanks so much for this comment. Lots of good info here, definitely grateful and appreciate it. I'm still picking up knowledge as I go and I definitely don't know everything. I'm really happy to see you're excited about this as I am, makes me want to work hard and get it on the road asap even more. Never heard a car on itbs live, but I got hooked ever since I watched the first carbed 4age vid on TH-cam.
+driving 4 answers (mr2 mk1 hero) don't sweat it my friend! I've been a tech for a long time and don't know everything. Nobody can. That's why we have service information!
You are correct in that the velocity stacks are there to smooth the flow and they do help with power (we have seen 10-20bhp gains when fitting them to a set of bike carbs that did not have any!). The filter does not do the same job, that is purely filtration and thus we always recommend running both a filter AND stacks. The TPS is as you say a 'typical' linear 5v sweep. It can be used on any aftermarket ignition ECU such as NODIZ or megajolt. All ECU's such as this will allow calibration of the sensor.
Well, actually you are not entirely incorrect. On the dyno we have seen marginal gains (eg 2-3 lb/ft across a 2000-3000rpm range) in torque by running back to back with no filter vs a filter and thus there probably is some truth in it stabilising the air. But this effect is not on the same level as stacks vs no stacks.
I’ve noticed that every time someone does a bike carb conversion they always angle the carbs facing up. Do they need to be angled like that or can they face forward?
The angle is super important as it determines the level of fuel in the float bowl and thus how the carbs run. If the angle is wrong you can never get them to run right. They can definitely not face down.
hey mate, it's good to know you wont be sucking debris or small children into those carbs.....lol ! :) Cheers from Australia, i was looking for someone who knows the 4age engine really well, and your videos are easy to follow, even if you're on the other side of the world :)
Buenas tardes. Yo quiero saber si estos carburadores me pueden funcionar para un motor z24 de Nissan. Si es posible que funcione, quiero saber como adquirirlo. Muchas gracias
Thanks. The carbs come pre-jetted from DanST engineering so you can fire up the car. Then you can do the fine tuning on a dyno. I ordered a full jet kit just in case and will make a detailed video on the jetting.
I meant a turbo, but supercharging would be just as cool. Either would be really unique as I haven't seen anyone have build videos regarding those using your channel's format.
Can you help me? If i have an engine that has an ac compresor and need an idle up, My question is can we install the idle up on the bike carb? Thank you
It all depends on how your idle air control valve system works and where it is connected. If it's designed to control the throttle plate directly than it won't work. You will also likely need to keep your stock ECU if it operates the idle air control valve. Carbureted cars also have a similar system called the idle speed control valve which you could consider retrofitting depending on your setup.
@@d4a ah gotcha. I am using S1000RR ITBs for my project and it looks like they have built in vacuum ports. Will I still need to run a vacuum balance bar?
Dylan Bill Itbs are not necessarily fuel injected. Itbs means nothing more than individual throttle bodies. I have four cylinders and four throttle bodies, instead of 1 throttle body for all 4 cylinders. Itbs says nothing about the manner of fuel delivery, it can be either injection or carburetted. I am using an ECU to run the distributor and provide timing advance. It's cheap, simple and reliable to use the stock ecu for this. I do plan to go megasquirt or similar eventually. A lot of all the details are in my bike carb conversion build plan video. Thanks for watching and commenting.
ITBs means 100% of the time fuel injection. I would say a throttle body is not a carburetor as a throttle body is a ... throttle and it needs an injector somewhere to deliver fuel while the carb makes the throttle and delivers the fuel so it's different. I'm curious to see how you'll deal with the ECU, will you flash the thing ? Good luck man in your build!
+driving 4 answers (mr2 mk1 hero) I think this debate is like what a tech defines a throttle body as vs what an engineer defines a throttle body as. I'm a tech so for me anything carbureted has carbs, anything injected has throttle bodies. So which side are you on D4A? The guys who design and engineer this stuff and rarely have to work on it, or the guys in the trenches who have to figure out to make this stuff live in the real world? How you answer will decide your future from here on out. Are you with us, or... J/K! Who really cares?! Its to-may-toe vs. to-mah-toe! As long we know what the other means we'll get along fine.
No issue for me either because either way his engine will sound GLORIOUS. I think this debate is just trying to prevent misunderstanding from people that are not as familiar with engines.
Hey, what is that third fitting on the fuel pump? At first I thought it was a return line, but you said there is no return and now I'm kinda clueless about that.
Huh, interesting, I found out that this pump with that fitting is usually used on kawasaki mules, on hondas it is just left alone. Couldn't find info on why is it there, but there is always rubber hose going somewhere from it
Hmmm. Good info, thanks. Now I'm curious about what it actually does. I'm going to try researching as well. Will let you know if I manage to dig up any additional info.
Also it seems that this model of pump likes to be gravity fed and can't really suck fuel itself that much. I assume you still goingt to use it together with the in-tank one? Although maybe I'm talking out of my ass here and its just looks the same but has different internals and is powerful enough to suck fuel in :)
MrDoroh You're right. It needs to be mounted at or below the level of the fuel tank, so pretty much gravity fed. I decided to disable in tank pump and have figured out how to mount this. There will be a detailed video on the fuel supply pretty soon.
Hmm, that's a v6 so it's a lot harder to do it. I haven't seen a ready made kit. But you can get in touch with DanStengineering and ask them. If anyone can make it, they can.
Dude, this is going to be so sick! I can't wait to see more of you build

Oh, and for testing you connect at the ground and signal wires. I get too pumped up when you put out a new vid!

Looks good, glad you post updates quickly!
Just finished watching this. Looks crazy. Going to be such a fun build.
as always, amazing explanation and Superb delivery with all the info!!
looking forward to you next vid!
DigerCZ Happy to hear that. More is on its way :)
can't wait for braaaaps
+fila1445 Me too :)
No there is some small pieces on the manifold I want to see you connect them together

hello sir, where can i get parts for my toyota 4k's bike conversion? did danstengineering selling for 4k conversion?
Very interesting. I am curious as to what the jetting will come out to be.
Thanks. The carbs come pre-jetted from DanST engineering so you can fire up the car. Then you can do the fine tuning on a dyno. I ordered a full jet kit just in case and will make a detailed video on the jetting.
Nice, I'll have to make sure I watch. In the future you should consider a blow through or draw through set up, that'd be insane haha. Subbed.
ionicbreeze Thanks for subscribing. You mean a turbo or supercharger?
I meant a turbo, but supercharging would be just as cool. Either would be really unique as I haven't seen anyone have build videos regarding those using your channel's format.
ionicbreeze I do have plan to do a turbo build sometimes in the future
I want to know how will connect the small pieces together if you please
Hi, what is the port size did you choose?
Hey bro do you happen to know if they make a manifold swap for a ka24e I'm trying to do this convertion to my 92 ka24e motor
Have you mounted it yet? I had to alter the intake holes a bit.
Haven't tried mounting yet. Will try soon. I hope I won't have to alter the intake holes.
Can you help me? If i have an engine that has an ac compresor and need an idle up, My question is can we install the idle up on the bike carb? Thank you

Hey man did you try this build on 4af engine?
Did you end up having to plug the bike itb vacuum ports?
You mean the ports for balancing the carbs?
@@d4a yes
These carbs don't have them. They are originally on the runners on the engine and not on the carbs in this case.
@@d4a ah gotcha. I am using S1000RR ITBs for my project and it looks like they have built in vacuum ports. Will I still need to run a vacuum balance bar?
@@cr4zyw3ld3r You only need the balance bar for a map sensor. You don't need one if you run tps and crank trigger based standalone ignition.
Hi thanks for everything but I want to see you when you connect all the pecise together spicaly the small pieces from a to z again thank you so much
th-cam.com/video/daqmPnEYMfk/w-d-xo.html do you mean like this?
These are just carbs itbs are fuel injected also u still using ecu for carbs ? I'm still learning to :)

Actually carburetors have throttle valves.
cheers mate. where to find a kit for Mitsubishi 4g 15 ?
All the links are in the description. Check DanStengineering.
Hey, what is that third fitting on the fuel pump? At first I thought it was a return line, but you said there is no return and now I'm kinda clueless about that.
The third fitting seems to be some sort of breather or something, it's definitely not a fuel line.

Do you think 600 carbs are big enough for a 2.3l 4cy?
Likely not
